APPARATUS FOR PURIFYING WATER.

SPECIFIGATION forming part of Letters Patent No. 624,527, dated May 9, 1899. Application filed August 19,1898. Serial No. 689,031. (No model.)

To (bi/Z wh'om it may conccrn:

Be it known that I, 'MARIUS OTTO, doctor of science, residing at Paris, France, haveinvented Apparatus for the Purification of \Vater, of which the following is a specification.

This invention relates to an apparatus intended for the purification ofwater on a commercial scale by submitting it to the action of ozone; but the apparatus may also be utilized forsubmittingliquids of any kind to the action of o'zone.

My im proved apparatus en ables the following advantages to be obtained:

First. The water and the ozone enter into intimate contact.

Second. The duration of the aetion of the ozone may be readily regulated and likewise the relative Volumes of Water and ozone taking part in the reaction.

Third; The water when once it has. been treated s protected from any fresh pollution.

In the accompanying drawings, Figure 1 shows the apparatus half in section and half Fig.-2 represents the said apparatus, one half in plan and the other half in horizontal section, upon the line X X of Fig. 1; and Fig. 3 is a sectional view of the injector in which the intimate mixing of the water and ozone takes place.

The apparatus may be arranged directly in a filtering-reservoir beneath the water-outlet.

'Within the cylindrical Vessel O' is arranged another cylinder 0 which is open at its u pper portion. The water enters the apparatus through the sieves G' G The ozone is admitted through the pipe O and the crown U, which distributes it to the injeotors E' E E Each of these injectors consists of a vessel E,

.Fig. 3, of cylindrical or spherical form, provided With a lateral orifice 0 I'n this vessel fit one within the other two tubes or nozzles O' O of conioal shape. The current of ozonated oxygen or of ozonated air enters the injector through the orifioe O' and issues through the orifice 0 carrying with it a current of water which whirls around in the space comprised between the cylinders O' and O. This current is broken up by the plates T' T which form baflies. The efect of the injectors may be increased by the-addition of me chanical agitators serving to stir vigorously the mixture of Water and ozone.

- The destruction of microbes and of Organic substances is accompanied by the production of very remarkable phenomena of phosphoresence. The water becomes luminous and retains its luminosity for several seconds.

The excess of air or of ozone escapes through the tubes t' t t arranged at the upper por- Iion of the apparatus and provided with funnel-shaped discharge-apertures P' P P The ozon'ated water rises above the upper edge of the cylinder 0 and esoapes through the pipe S, which communicates directly with the distributing-mains.

By means of extremely simple accessory appliances a certain number of injectors only maybe ca used to operate, the su pply of water to each of them being either partially or totally cut off.

The water is prevented from being forced back into the -ozonc-supply pipe O and into the 'exhaust-tubes t' by means of suitable valves.

The water is not able to reach the distributing-mains eXcept by passing through the injectors. It is thus' certain that each partiole of water will be submitted to the action of the ozone.

The period during which the water and the ozone remain in contact depends upon the height of the annnlar space -comprised be* tween the oylinders O' O.

If it is desired to'arrange my apparatus out side the filtering-reservoir, it is only necessary to conduct the water to the in j ectors through a circular conduit. v In such a case the air and the ozone escape freely or are collected for the purposeof again being submitted to the aotion of the electric effluvium. This ar rangement may be adopted when the impurty of the water is such that it is necessary to ar= y range several apparatus in series I o1aim-- In combination, the outer tank O' having a cover with outlets for the ozono', the inner tank 0 having its upper end Opening into the space between the two tanks, and having a discharge for the water at its lower end, 'the space between the tanks being closed at 'the ICO bottom, the inlets for the Water through the lower parts of the outer tank, the injectors connected Wit-h the water-nlets and sitnated at the lower part of the space between the tanks, ozone-supply pipes leadng to the injectors and baffle-plates in the space between the tanks, snbsta-ntally as described.

In witness wherecf I have hereuntcset my hand in presence of two witnesses.

MARIUS OTT.
